After Su Yu left, Tang Xiaomei watched his distant figure with a hint of disappointment: "Why did he leave so quickly..."
She then lowered her head, looking at her hands, recalling how she had attacked Su Yu with all her might in fear, only for him to casually deflect it. She couldn't help but sigh: "How did he train to become so strong..."
...
At this moment, Su Yu was flying towards Wind City in the south at over ten times the speed of sound, while reviewing the information on Extreme Ice Agents that Tang Xiaomei had given him.
The rituals and Meditation Technique of the Extreme Ice Agents were recorded within.
However, there was no mention of its hidden dangers, probably because Tang Xiaomei herself was unaware, or she wouldn't have nearly fallen victim.
The ritual of the Extreme Ice Agents was quite straightforward; it required creating or finding a space with Absolute Zero and surviving there for a year.
